Apocrine Sweat

2

_____ glands: hybrid sweat glands mainly in axilla

Apoeccrine

3

_____ glands: lubricate thick terminal hairs with oily secretion

Sebaceous

4

_____ glands: oil glands that secrete sebum (lipid mixture)

Sebaceous

5

_____ glands: produce more viscous sweat, become active after puberty, located in axillary and anogenital regions

Apocrine Glands

6

_____ glands: secrete odorless watery sweat, vital in thermoregulation

_____ glands: traditional Sweat glands distributed over most of the body with water enzyme-rich secretions

Eccrine Sweat

9

______ layer of the dermis: dense connective tissue

Reticular

10

______ layer of the dermis: loose connective tissue immediately under the epidermis

Papillary

11

_________: apical portion of secretory cell cytoplasm pinches off and enters lumen

Decapitation secretion

12

______: attach keratinocytes to each other

Desmosomes
